Abstract

The invention belongs to the technical field of shore-based short range small radar tracking, and provides a full-automatic radar tracking processing method. The method comprises the step of carrying out the statistics regularly to generate a dynamic clutter map so that a dynamic target can be detected, the step of carrying out the quick rough comparison according to the orientation partition and the distance segmentation, accurately calculating the space distance to carry out the fine comparison and combining a plurality of correlated points into a cluster point, the step of updating a stable track if the cluster point can be correlated with the stable track, the step of further judging whether the cluster joint can be correlated with a temporary track or not if not, the step of updating the temporary track if yes, and the step of storing all non-correlated points of the stable track and the temporary tack in a temporary list to be correlated with a temporary list in the next scanning period if not. The method is achieved in a computer, a radar signal is later processed by the computer instead of hardware circuits of radar, the number of the radar circuits for processing the signal on the radar is reduced, the size of the radar is reduced, and minimization and full automation of the radar are achieved.

Description

technical field

[0001] The invention belongs to the technical field of radar tracking, and in particular relates to an automatic tracking and recording processing method and a computer of shore-based miniaturized short-range radar. Background technique

[0002] Radar tracking has a wide range of applications, such as monitoring of ships near the coast in coastal defense, radar monitoring of remote unattended islands, etc. In radar measurement, dynamic targets often need to be tracked and numbered, but at present, most of them are recorded by manual operation or semi-automatic tracking and recording, and automatic tracking and recording cannot be realized, or processed by the underlying hardware equipment (ARPA). Contents of the invention

[0003] In view of the above problems, the object of the present invention is to provide a shore-based short-range radar automatic tracking processing method and computer, the method is realized by the signal processing dynamic link libra...
